Morphology

orthotropous = orthotropic (opaque) = ortho + trop + ous

Formation from a recognizable technical base ('orthotropic') by replacing or adding an adjectival ending is regular, though the exact botanical application is specialized.

Etymology

Orthotropous comes from the Greek parts ortho- meaning 'straight' and -tropous meaning 'turn', the same 'turn' you see in 'tropic' when plants turn toward light. So an orthotropous ovule stays straight, not bent, with its small opening, the micropyle, at the top.
